1. HYBAX. 285 



the collection that I propose to designate it provisionally Hyrax 

 semieiroularis. 



The interparietal bone being on the edge of the occipital region 

 of the skull is a character (as well as the incomplete orbit) that 

 separates the skuU of Hyrax from Dendrohyrax, even in the 

 youngest state. 



* Dorsal spot black, well marked. Africa. 



1. Hyrax capensis. (The Klipdas.) 



Fur black, minutely punctulated with white, with a black dorsal 

 streak.

 am by no means sure that several species may not be confounded 

 under this name in these papers, as all the specimens formerly re- 

 ceived at the Zoological Gardens were called H. capensis. 



** Dorsal streak yellow, linear. 

 a. Fur harsh. 



2. Hyrax Burtonii. 



Fur rather harsh, pale yeUow-grey, very slightly punctulated 

 with blackish ; dorsal streak small, yellow ; the hairs of the back 

 rather rigid, black or dark brown nearly the whole length, with a 

 moderate yeUow tip ; underside pale yellow ; interparietal bone half- 

 ovate, as long as broad.

 quite adult, as the hinder or third upper true molar is not quite de- 

 veloped. It is very like No. 724 c in size, form, and in the form of
